	this stuff is weird: some wnds, like entity list, keep pos on hide/show... until you resize them -)
	some, like floating xy/cam/groupdialog do not; if you remove glwidget from floating xy - it does xD
	if you gtk_window_set_position( window, GTK_WIN_POS_CENTER_ALWAYS ), they do keep it, except of random centering after resizing (ms windows)
	but this option doesn't sound healthy;
	gtk_window_set_transient_for seems to do some gtk_window_set_position also

	workaround for strange gtk behaviour - modifying the contents of a window while it is not visible causes the window position to change without sending a configure_event */
